More than two decades after her death, Diana Vreeland is once again a star.

A new documentary about the legendary fashion editor is hitting movie screens this month, a companion book was published last year, and fresh biographies are available.

Why revisit Vreeland? Because in a field that is supposed to be all about originality and creativity, it is seldom either.

And Vreeland embodied both.

We got some personal insights into the “empress of fashion” during a recent phone interview with Lisa Immordino Vreeland, the force behind the documentary and book, “Diana Vreeland: The Eye Has to Travel.”

Christina Ricci arrives at the Metropolitan Museum of Art Costume Institute gala benefit, May 7, 2012 in New York.

In a city that hosts thousands of fashion shows each year, there’s no bigger — or perhaps more treacherous — runway than the red carpeted staircase of the Metropolitan Museum of Art in New York City.

The museum’s annual Costume Institute gala draws the top tier of the fashion design world as well as a full assortment of A-list celebrities. And they all climb the stairs, sometimes with difficulty, given the confinement or complexity of their outfits. For the first time, the arrivals were live-streamed Monday in a collaboration between the museum, Amazon and Vogue magazine, so viewers got to see what guests were wearing and hear from the designers who created the looks. I tuned in along with thousands of others.
